LUBRlCATlNG-AXLEQ j l SPECIFICATION forming part of Letters Patent No. 61o,ieafaateaseptember e, 189s.

Application tiled March 1 21 1 8 9 3- T0 a/ZZ whom it may concern:

Be it known that I, JOHN G. OBERMIER, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented new and useful 4Improvements in Lubricating-Axles, of which the following is a specification.

My invention relates to an improvement in dust-protecting and lubricating axles; and it consists of a tapering spindle proper provided with two longitudinal grooves and a connecting-groove for the purpose of carrying the oil and distributing it over the body of the spindle and in providing a circumferential groove at the outer end of the spindle and connecting with the longitudinal groove, by which the flow of the oil from the spindle is checked and returned to the `longitudinal groove, as is hereinafter more fully described and claimed.

In the accompanying drawings similar letters of reference refer to similar parts.

Figure l is a side elevation of the spindle and box with a portion of the box cut away, showing the relation of the various parts. Fig. 2 is a longitudinal sectional view of the box and spindle. Fig. 3 is a cross-sectional view of the spindle and box at X X.

A representsthe axle proper, which terminates in a spindle a. At the end of the axle and intermediate the spindle there is formed a proj ecting collar a", having a tubular iiange a2, upon the outer surface of which there is provided a circumferential groove a3 for the purpose of interrupting and preventing the passage of dust into and upon the spindle. Upon the upper portion of the spindle ct there is provided a longitudinal groove a4, terminating just short of the inner and outer ends of the spindle. On the under side of the spindle there is provided another longitudinal groove a5, and a smaller groove a6 connects these two longitudinal grooves a4 and a5, the object being to provide a means of conducting the oil :from one of the longitudinal grooves into the other, from which it is distributed to all points of the spindle.

Heretofore this object has Vbeen sought to be accomplished by the placing of small distributinggrooves near the center of the longitudinal groove; Abut thishas been found to be defective, and the providing of two longi- Serial No. 675,635. (No model.)

tudinal grooves with the connecting-channel between the same prevents the draining of the oil into any one position when the vehicle is at rest and provides for its better distribution when the vehicle is in motion.

At the outer end of the spindle proper there is provided a circumferential groove a7, connecting with the longitudinal groove ai and which acts as an absolute check against the exudation `of the oil. To provide an additional check and means for returning the oil from the surface of the spindle to the longi tudinal groove, a spiral groove o8, passing `partially around the spindle and communi eating with the longitudinal groove a4, is pro vided. The object ofthis spiral groove of is to facilitate the return of the oil to the longitudinal groove and prevent the overloading of the circumferential groove a7.

B represents the box, which is of tubular form, its interior adapted to conform in size and shape to that of the spindle. At the inner end of the box there isa raised collar carrying two tubular iianges. The inner iiange b is on the same plane as the interior of the box and, resting upon the spindle, passes be tween the spindle and the iiange a2 upon the axle.` The outer flange lis longer than the inner flange and passes over the iiange a2 and the circumferential groove a3 thereon and abuts against a projecting collar c. of the axle, thus forming a substantially dust-proof connection between the innerend of the box and the axle.

The outer end of the spindle is screw-threaded, so as to carry the ordinary form of nut C, by means of which the box is held in engagement with and in position upon the spindle.

Having thus fully described my invention, what I desire to secure and claim by Letters Patent is l. A solid axle-spindle, provided with oppositely-disposed parallel longitudinal grooves terminating short of the'spindle ends, a dis-l tributing-groove connectingthe same, a circumferential groove at the outer end of' the spindle and connecting with one of the longitudinal grooves near its outer end, and a spiral groove extending partially around the spindle, one end merging into the plane of the spindle, and the other connected with said IOC longitudinal groove,substanti ally as set forth.

l grooves, substantially as set forth.

3. An axle-spindle having at its inner end an enlarged head provided with a projecting collar a, and au inner annular flange provided with an annular groove, forming a dusttrap, in combination with a box,havinga short inner annular flange and an outer annular flange, the latter of Which projects over the inner annular flange Vand groove, abutting against the projecting collar of the axle, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of tWo subscribing 2o Witnesses.

JOHN G. OBERMIER.
